Effects of Rib and Age on Serum and Hair Mineral Contents and Correlation of Mineral Contents between Serum and Hair of Jinchuan Yak
摘要
Abstract
This study was conducted to measure the mineral contents in serum and hair of Jinchuan Yak, anal⁃ysis the effects of rib and age on them and the correlation of mineral contents between serum and hair. Thirty two male yaks were divided into 8 groups using two⁃factors repeated measures by rib [14 ribs (n=17) and 15 ribs (n=15)] and age [0 (birth) to 2 years old (n=10), 3 to 4 years old (n=11), 5 to 6 years old (n=5) , 7 to 8 years old ( n=6) ] . Serum and hair samples were collected to determine mineral contents. The re⁃sults showed as follows:1) mineral [ calcium ( Ca) , copper ( Cu) , ferrum ( Fe) , kalium ( K) , magnesium ( Mg) , manganese ( Mn) , natrium ( Na) and zinc ( Zn) ] contents in serum were not affected by rib, age and their interaction (P>0.05). 2) Ca, Cu, Fe, Mg, Mn, Na and Zn contents in hair were not affected by rib ( P>0.05); K content was affected by age, and 7 to 8 years old was significantly higher than the other ages ( P<0.05) , but the other mineral contents were not significantly affected by age and the interaction of age and rib ( P>0.05) . 3) There were significant correlations of Ca, Cu, Fe, Mg and Zn contents between serum and hair ( P<0.01) , and correlation coefficients were 0.623 0, 0.539 8, 0.569 2, 0.468 4 and 0.505 3, respec⁃tively, but there were no significant correlations of K, Mn and Na contents between serum and hair (P>0.05). It can be indicated that there is no significant difference of mineral content between 14⁃rib and 15⁃rib Jinchuan yak; mineral contents of 7 to 8 years old yak have significantly higher K content in hair; there are significant correlations of Ca, Cu, Fe, Mg and Zn contents between serum and hair, and hair can be used to measure their contents instead of serum.关键词
